我的ubuntu服务器20.04经常自动重启，通过阅读/var/log/messages，发现错误：
ERST: Error Record Serialization Table (ERST) support is initialized.
RAS: Correctable Errors collector initialized.
所以我在grub上禁用了acpi，但是cpu核心数只有一个，所以我无法禁用acpi，但是如果我不禁用acpi，ubuntu server 20.04会频繁自动重新启动。那我能做什么呢？请帮我

答案1
服务器是否包含任何看门狗BIOS 中的设置？
如果在 BIOS 中启用了此类硬件看门狗，则必须安装适当的看门狗驱动程序（该驱动程序可能是专有的并且仅适用于某些发行版）或禁用看门狗。
